Embodiment 1

[0033] Such as figure 2 As shown, a solar gas composite energy hot water system includes: a solar heater 1, a gas water heater 2, a central hot water circulation loop 3, a thermostatic tank 4 directly connected to the central hot water circulation loop 3, and a solar heater 1 A heat storage tank 5 forming a solar circulation loop, and a control system.

[0034] Wherein, the first water outlet 41 of the thermostatic tank 4 is connected to the water inlet 21 of the gas water heater 2, and the first water inlet 42 of the thermostatic tank 4 is connected to the water outlet 22 of the gas water heater 2 to form a heating cycle. The water outlet 51 of the heat storage tank 5 is connected to the second water inlet 43 of the thermostatic tank and the water inlet 21 of the gas water heater through the three-way valve 6 .

[0035] The control system includes: a first control module for controlling the solar circulation loop, a heating module for controlling the heating circulation loo...

Embodiment 2

[0043] Such as Figure 6 As shown, a solar gas composite energy hot water system includes: a solar heater 1, a gas water heater 2, a central hot water circulation loop 3, a thermostatic tank 4 directly connected to the central hot water circulation loop 3, and a solar heater 1 A heat storage tank 5 forming a solar circulation loop, and a control system.

[0044] The solar-gas composite energy hot water system provided in this embodiment is basically the same as the first embodiment, the only difference is that the thermostat tank 4 is superimposed on the heat storage tank 5, and the installation structure is compact and occupies a small space.

Abstract

The invention relates to the field of water storage heaters and discloses a solar gas composite energy water heating system. The system comprises a solar heater, a gas water heater, a water tank, a central hot water circulating circuit and a control system and is characterized in that the water tank comprises a constant temperature tank and a heat storage tank, wherein the constant temperature tank is directly connected with the central hot water circulating circuit, and the heat storage tank forms a solar circulating circuit with the solar heater. A first water outlet in the upper end of the constant temperature tank is connected with a water inlet of the gas water heater, and a first water inlet in the upper end of the constant temperature tank is connected with a water inlet of the gas water heater to form a heating and circulating circuit. A water outlet of the heat storage tank is connected with a second water inlet in the lower end of the constant temperature tank and a water inlet of the gas water heater. Compared with the prior art, the solar gas composite energy water heating system has the advantages that the solar utilization rate is high, the heating rate is high, and continuous large flow constant temperature water supplying capacity can be obtained through little heat output of a gas heating device. The invention further provides a control method based on the water heating system.

Description

technical field [0001] The invention relates to the field of water storage heaters, in particular to a solar gas composite energy hot water system and a using method. Background technique [0002] In recent years, as energy saving and environmental protection put forward higher and higher requirements for household appliances, solar gas water heaters are gradually favored by users. However, independent solar water heaters are greatly affected by the climate, and it is difficult to ensure sufficient hot water at all times. To this end, the industry has developed a multi-heat source hot water system that combines solar gas and gas. [0003] As a publication number is the Chinese patent disclosure of CN2740949 a kind of multi-heat source (solar energy, gas, electricity) central gas water heater, as figure 1 As shown, it includes: a solar heating device 01, a gas heating device 02, a constant temperature pump 03, a temperature sensor 04, and a temperature control system 05. Th...
